Size Distribution of Large Haze Particles

[摘要] During the period from february 17 to April 10 in 1955 the observations of large haze particles were made at several stations in Asahigawa. The results of observations are as followe:(1) The size distribution of particles in the air is expressed by the formulae dN/dr=const. r-3.6 for 0.540μ, where r is the radii of the particles.(2) The mean density of non-hygroscopic particles is about 0.15.(3) Most of the particles are non-hygroscopic and the ratio of the concentration of non-hygroscopic particles to the of hygroscopic particles increases with particle size.
